Sentence rhythm
- How long your sentences are.
- Whether you favor commas or em-dashes.
- Whether you open with subjects or with adverbs.
Voice DNA
Wren reads how you write, then writes like you.
Voice DNA is the feature that makes your book sound like the post you wrote at 2am. Not a generic AI voice. Yours.
What Voice DNA actually does
Three layers of you.
Vocabulary
- The words you actually use.
- The words you avoid.
- The domain-specific shorthand you take for granted.
Explanation style
- How you set up a concept.
- Whether you lead with examples or with definitions.
- How you close a thought.
Why voice matters
You already recognize their voice in two sentences.
Voice is the fingerprint behind every sentence. Wren learns yours the same way you'd recognize theirs, by listening to what you've already written.
Warren Buffett
Folksy parables, midwestern restraint, a single number that anchors the argument.
Elon Musk
First-principles framing, deadpan understatement, a punchline in the last sentence.
Ray Dalio
Numbered principles, framework-first thinking, careful permission to disagree.
Steve Jobs
Crystallized verbs, short declaratives, the customer as the only character.
Yours next. Wren reads what you've written and keeps the rhythm that's already there.
What Wren reads
Anything you've already written.
Wren pulls source material from wherever you already wrote it. If it exists in text form, he can read it.
- LinkedIn posts (paste URL or text)
- Substack, Medium, blog posts
- Podcast transcripts (we run the audio through transcription)
- Apple Notes / Google Docs / Notion exports
- Voice memos
- Email drafts you wrote to yourself
- Previous book chapters
- Sales call transcripts (Gong, Fireflies, Granola)
Where Wren draws the line
Things Wren refuses to do.
Won't insert filler.
If a section is thin, Wren marks it for you to fill in. He doesn't pad.
Won't paraphrase generic content.
If you didn't write it, Wren won't try to make it sound like you.
Won't insert phrases you've never said.
Voice DNA flags low-confidence phrases for your review before they ship.
Won't override your edits.
When you change something, Voice DNA learns from the edit. Wren doesn't argue back.
Worked example
Here's what it looks like.
Same prompt, two voices. Left: what Wren reads from a real LinkedIn post. Right: how Wren writes a new paragraph using that voice.
Input: your LinkedIn post
Most of my clients don't have a strategy problem. They have a decision-making problem. When the founder says “we need alignment,” what they usually mean is “I made a decision and I want everyone to feel like they were part of it.” Those are not the same exercise.
Output: Wren writing a new paragraph in your voice
Most teams don't have a meeting problem. They have a follow-through problem. When the manager says “we just need to talk it out,” what they usually mean is “I'll feel better after we discuss it and then we won't actually change anything.” Those are not the same outcome.
Privacy
Your writing samples stay yours.
- Samples used only to train your private voice profile.
- Never used to train base models.
- Delete your samples anytime. Profile is destroyed with them.
- Your book content is yours under copyright.
Same Wren. Three different voices. Three published books.
Click any cover. Read it. Hear them.
Three authors. Three completely different voices. One companion. The cadence in each book is the author's, not the model's.
ON HEARING THEIR OWN VOICE BACK
“The first chapter Wren handed me, I read three sentences and forgot it wasn't mine. That's the proof, right there.”

FAQ
Voice DNA questions.
Five to fifty pages of your existing writing. More is better, but Wren doesn't need a novel to learn you. Ten strong LinkedIn posts beats fifty bland ones. Quality over volume.
Yes. Each book gets its own Voice DNA profile, so you can write a memoir in one voice and a business book in another. Profiles never leak across books.
Use your current writing as the source. Wren weights recent samples more heavily. If your voice changes mid-project, refresh the profile and Wren picks up the new shape on the next chapter.
It works, but Wren is optimized for non-fiction: business books, coaching books, founder memoirs, expertise-driven books. Fiction authors find structure assumptions lean argument-driven.
Co-author voice blending is on the Authority roadmap. Today, profiles are scoped to a single author per book.
When you're ready
You've been writing the chapters in your head.
Wren puts them on paper.
Companion-mode if you're starting from scratch. Editor-mode if your manuscript is already done. Either way, the next click is a draft on screen.
